Concepts

Content: Earth, Physical, & Life

Different liquids may have different or similar densities.
Different concentrations may have different or similar densities.
Liquids of different temperatures have different densities.

Cross cutting concepts

Evidence is collected through observation.
Change is a difference in properties over time.
Very careful observations can help us notice changes we sometimes overlook.
Observations are used to collect evidence to use to explain why certain
events happen.

Science Practice

Communication
Diagrams can be used to show change.
Charts help to organize information to see patterns.
Symbols may be used to communicate observations.

Experimenting
A fair experiment controls all variables and uses a control.
